Explain % V/V in brief.

Explanation

The volume of solute (mL) dissolved in 100 mL solution, is expressed as volume percentange (% V/V).
Volume % of a component `= ("Volume of the component" xx 100)/("Total volume of solution")`
For example, 10% ethanol solution in water means that 10 mL of ethanol is dissolved in water such that the total volume of the solution is 100 mL. Solutions containing liquids are commonly expressed in this unit.
For example, a 35% (V/V) solution of ethylene glycol, an antifreeze, is used in cars for cooling the engine.
At this concentration the antifreeze lowers the freezing point of water to 255.4 K `(-17.6^(@)C)`.
